and gears 1' in such a way, that each column position of carriage W1 corresponds to one of the turning positions of cylinder 1. In each turning position four controlling elements 2 detachably fixed on the cylinder 1 and corresponding to four column-positions I to IV of carriage W2 cooperate with feeling levers 3, which influence contacts or the like, operating the device for moving carriage W2 into the column-positions by means of electrical connections. In addition, function controlling cylinder 1 is provided with detachably controlling elements 5 actuating contacts 7 by way of feeler levers 6 for the line spacing on the secondary printing mechanisms.

After carriage W2 has been adjusted into that column position which is allotted to the adjusted column of carriage W1 in accordance with the controlling elements 2 the printing type members 51 of the secondary printing mechanism D2 have to be adjusted by means of longitudinal movement, to the same figures or signs to which the type members 50 of principal printing mechanism D1 having been positioned.

With printing mechanisms D1 and D2 being arranged close together the type members 51) and 51 allotted to each other may be connected with each other in a direct and mechanical way. In the mode of execution shown in which the printing mechanisms are thought separated from each other, adjustment or the type members 51 (Fig. 1) is performed by electrical means whereby below the contacts 50' (Fig. 5) fixed to the individual type members 50 a contact slide 45 is passed along a cross member 51' (Fig. 1) being moved the same distance by mechanical or electrical connection means 46, :6 when a cross member 51' will release the spring actuated printing members 51.

In the moment in which one of the contacts 50' is closed an electro-magnet 54 allotted to the corresponding type member 51 will be excited by means of connections X and induced to arrest the type member 51 in such a way that upon further movement of cross member 51' said type member 51 cannot be moved further on.

A selecting mechanism S is provided too in the system of connections for the control of the column-positions and the line switching by means of which the mentioned controls may be additionally influenced.

Now the individual mechanism of the machine will be described more in detail.

Carriage W2 (Fig. 2) of the secondary printing mechanism which is slidably supported in a known manner is moved by a driving mechanism 10 equipped with a reversing clutch 11 by way of rack 9. In this way, drive gear 14 may be actuated to the right or to the left alternatively and depending upon whether magnet winding 12 or 13 (see also Fig. l) is being excited. Line spacing shaft 15 drives the platen 18 over corresponding bevel gears 16 and a screw drive 17. The drive of the line spacing gear is effected over a clutch 19 which may be actuated through a magnet 20 through its armature 21. Limiting stops I to IV are arranged on part 8 (Fig. 2) of the paper carriage W2 each allotted to one of the four column positions.

Arrangement and functioning of limiting stop I may be gathered from Fig. 3; the others are in principle of identical construction. In this case, limiting stop I is provided with a switching nose 22 which actuates contact springs 25 and 26 through control rod 24 by way of a feeler lever 23 when the carriage is moved, thereby closing or opening the corresponding contact. In slot 27 of the limting stop, control means 28 may be inserted to actuate the corresponding contact 39 by way of feeler lever 29. With a lower nose 31 of the limiting stops blocking levers 32 and 33 are in cooperation which may be actuated by one magnet each 34 or 35 (see also Fig. 1), respectively, depending upon the direction of movement of the carriage.

According to Fig. 4, shaft 15 actuates a selective dial 38 for line spacing by Way of an appropriate gearing 36, 37, the dial being provided on its periphery with one or a plurality of detachable controlling bits 39 cooperating with a triple-armed notch-engaging lever 40. This lever is actuated by armature 41 of magnet 42 (see also Fig. 1) its feeler nose 40a engaging controlling bit 39 while feeler nose 4% will lean against a pawl 43a on control lever 43 which in turn can actuate a retaining contact 44 for clutching magnet 20 (Figs. 1, 2).

Fig. 5 illustrates the arrangement of the contact mechanisms within the principal printing mechanism for the adjustment of the type members of the secondary printing mechanism. Contact carriage 4-5 driven by gears 46 slides along a rigid feeding plate 47 provided with contact springs 43 sliding on feeler strips 49 on the contact carriage. Depending upon the position of the contact carriage 45 and the contact bridges, respectively, springs 48 may be bridged over, thereby initiating switching operations to the secondary printing mechanism by way of connections X (Fig. 1).

In Fig. 6 an adjusting mechanism for the type members 51 of the secondary printing mechanism is illustrated which provides recesses corresponding in number to the number of their printing signs and which cooperate with pawls 52 which are released to enter said recesses by the armature 53 of their magnet 5 as soon as the latter being excited over connections X (Fig. 1).

Finally, in Fig. 7, a cutting device is illustrated which may be provided for cutting off accounting sheets on the principal and/or secondary printing mechanism in case a feed roller is employed. The drive of the cutting device is effected from the drive disc 55 by way of screw spindle 56 permitting to slide a carriage 57. This carriage is supported at 58 and carries a cutter 60 on shaft 59, said cutter being turned when the carriage is moved laterally through gear 61 in mesh with toothed rack 62. End contacts 63 for reversing the drive are provided on the frame of the cutting device. This cutting device may be actuated on dependence of line spacing for the paper carriage W1 or W2, e. g. by means of the selective dial 38 (Fig. 4) with the use of detachable controlling bits and levers similar to the bit 39 and lever 40.

The cooperation of the individual elements of the equipment is as follows:

The function controlling cylinder 1 (Fig. 1) arranged within the main machine and moved in conjunction with the paper carriage of the principal printing mechanism will close according to its position and the shape of the control organs 2 one of the contacts 4 over the feeler levers 3 for column adjustment of the paper carriage of. the secondary printing mechanism. Likewise, by the positioning of the carriage W2 of the secondary printing mechanism one of the limiting stops I to IV will open one of the contacts 3% by way of one of the feeler levers 29 (Fig. 3). If, for instance contact 4 for column II of the carriage W2 has been closed and the carriage is to be found in column II the corresponding contact of the limiting stop II is opened. The circuit is broken, the reversing clutch 11 (Fig. 2) for the movement of the carriage (Figs. 1 and 2) and the blocking lever 32 and 33 respectively for the limitation of the carriage movement will not be actuated. If, on the other hand, carriage W2 of the secondary printing mechanism is situated for instance on column I, and the function controlling cylinder 1 has actuated the contact 4 for column III while feeling, conformity will be extant no longer, with the result that the corresponding contact 30 of the limiting stop III is closed. The corresponding blocking lever 32 or 33 (Fig. 3) for the limitation of the carriage move ment and the reversing clutch 11 will be engaged through their magnets 34 and 35, respectively, and 12 and 13, respectively. Carriage W2 (Fig. 1) of the secondary printing mechanism will thereupon run to a point where its position will coincide with the one demanded by the principal printing mechanism; thereby the corresponding contact 3t) will be opened again by means of the control means 28 of the limiting stop III in such a way that the magnets become again currentless, and the blocking lever 32 blocking anew whereby clutch 11 is simultaneously disengaged.

The above mentioned selecting mechanism 8, the chief object of which is to control the circuits of the magnets 12, 13 (Fig. 2) for the reverse clutch 11 and the magnets 34, 35 for actuating the blocking levers 32, 33 (Fig. 3) provides four magnets 11, b, c, d (Fig. l) mounted on the frame of the selecting mechanisms each of which is connected by conductions A with one of the contacts 4 over one of the contacts 3t) (Fig. 3), in such a way, that magnet a (Fig. 1) belongs to column position i, magnet 12 to column position H, magnet c to column position ill and magnet d to column position IV of the paper can riage W2.

The magnets a to d respectively can only be excited when both of the allotted contacts 4 and 36 are closed. Below the magnets a to d a slide s1 is shiftable mounted on the frame of the selecting mechanism which carries two levers g on a common fulcrum e. Levers f, g represent armatures for the magnets a to d and are attracted by that of the magnets a to d, the circuit of which being closed by the contacts 4 and 30. Slide .91 carries also two contacts 11 and 1 each cooperating with end of the lever f or g, respectively, each contact will be closed by its lever end when the appertaining lever f or g is attracted by one of the magnets a to d; the Contact closes the circuit for the magnet 12 (Fig. 2) and the contact i the circuit for the magnet 13 of the reversing clutch 11. Further the magnets 34 and 35 (Fig. 3) respectively for the blocking lever 32 or 33 are connected with the contacts h and i. The circuit of contacts It and 1 runs over the contact (Fig. 3) actuated by feeler lever 23 in such a way, that the magnets 34, 35' respectively and magnets 12, 13 respectively can only be excited when the paper carriage is in a column position, as shown in Fig. 3, provided that one of the contacts 11 and i has been closed.

Slide sll (Fig. 1) carries a racl; r with which the armatures of magnets is and l cooperate which are mounted on the frame of the selecting mechanism S said armatures pivotally mounted on the frame of the selecting mechanism acting as pawls in order to move the slide in the one or the other direction each time they are attracted and then moved back by their springs. By means of the rack r and by exciting the magnet is the slide will be moved in this way by means of the armature of magnet I to the left and by exciting the magnet l the slide will be moved to the right. The circuits of the magnets k and 1 runs over the contact 26 (Fig. 3) and over the contacts 11 and 1' respectively, so that when the paper carriage W2 is leaving a column position and lever 23 (Fig. 3) falls oh the nose 22 contact 26 being closed closing the circuit of the magnet k or Z, respectively whereby the same attract their armatures which cooperate with the rack 1', hence the slide s1 will move one step to the right or left, opposite to the direction of the movement of the paper carriage W2. This movement continues from column position to column position in the same direction till the column position corresponds to the adjusted control member 2 (Fig. 1). In this case the contact 34) is opened when the contact 3% runs up on the allotted control means 28 and none of the magnets a to d can be excited. Thereby the fulcrum 2 (Fig. 1) of the slide s1 lies below that magnet a to d which belongs to the attained column position. When, as in the already mentioned instance the carriage W2 is found in column I and is to be adjusted to column Ill according to the set controlling member 2 (Fig. 1) the circuit for the magnet c is closed by the contact 4 allotted to the control element 2 and the third contact 30 from above in Fig. 3. The excited magnet c (Fig. 1) attracts lever g which closes contact 1', so that the magnets 12 and are excited and the carriage will be moved to the right. Thereby feeler lever 23 (Fig. 3) falls oif the nose 22, whereby the contact 25 is opened while contact as is closed. Armature 33 is released and moves into the way of the nose 31 of the following limiting stop ll for stopping the carriage again. By the closing of the contact 26 magnet I (Fig. 1) is excited over contact i whereby the slide s1 is moved one step to the right. When the carriage W2 has attained column position the same operations repeat, and on attaining the position ill the movement of the carriage will cease because that contact 30 which is connected with the contact "l of the set control member 2 (Fig. 1) is held open by the control means 28 which is found on the limiting stop ill. in the third slot 27 from above.

For spacing the lines, contacts 7 (Fig. l) have been provided by which the magnet 20 (Fig. 2) for spacing on and off of the line switching clutch 19 can be actuated. When exciting magnet 2%, the end of armature 21 is lifted off nose 19a of clutch 19, the clutch becomes engaged and the line spacing shaft 15 is turned. With each revolution, the selecting dial 33 is turned one step ahead by way of gearing 36, 37 (Fig. 4). If now contact 7 (Fig. l) is closed, magnet 42 by way of connection C will be excited attracting its armature 41 (Fig. 4-) whereby the triple-armed lever is released and swung under the influence of its spring (not shown) in counterclockwise direction leaning with its arm 401) against the pawl 43a of the control lever 43. Upon turning movement of the selecting dia control lever 43 is turned in clockwise direction by the teeth of the dial lowering pawl 43a, so that the hooklil-(e end of the arm 4011, can snap over pawl 43 in order to hold down the control lever 43 in a position in which contact is closed in such a way that magnet (Figs. 1 and 2) over connection E will receive permanent current and the line spacing shaft will be revolved until the retaining contact 44 (Fig. 4) is released again. This will be the case every time a controlling bit 39 on selecting dial 33 lifts the lever arm 40a. In this manner, contact 44- will be released and notch-engaging lever 40 blocked by magnet 42.

The actuation of the type members 50 (Fig. 5) of the principal printing mechanism and of the type members 51 (Fig. 6) of the secondary printing mechanism or mechanisms takes place synchronously. While keys or other abutments control the way of value of adjustment of the type members 50 of the main machine, this way or value will be transferred to the members 51 of the secondary printing mechanism or mechanisms. For this purpose the corresponding magnet 54 (Fig. 6) will be excited by the movement of the slide (Fig. 5) and by means of the contact bridge 5%, the slip springs 43 and the contact strips 49, whereby the armature 53 is freeing lever 52,, entering a recess of its member 51 which follows its spring, whereby the member 51 is locked in a position corresponding to the value the corresponding member of the main machine having been adjusted.

A cutting device (Fig. 7) may be provided on the principal as well as on the secondary printing mechanism, the drive by way of driving disc 55 and screw spindle 56 again allowing of being switched on and oil by a magnetically actuated clutch similar to clutch 19 (Fig. 2).

Operation is preferentially effected with the aid of a switch button from the main machine, it being possible to actuate the cutting blades on the principal and secondary printing mechanisms either separately or simultaneously.
